Subject: OMAP: IOMMU: function flush_iotlb_page is not flushing correct entry
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f48ef99ca14577f3ea0a48c0e05ed7f5f6d211e9;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

OMAP: IOMMU: function flush_iotlb_page is not flushing correct entry

The function flush_iotlb_page is not loading the CAM register with
the correct entry to be flushed, so it is flushing other entry
